1. Why is organic chemistry so important in the study of biology (include at least 3 reasons with pictures to support each)?
a good begining. Lets revise this focusing on what you have learned about the relationship BETWEEN structure, properties, and reactions of organic compounds
Organic Chemistry is so important in the study of Biology because most reactions in Biology are organic reactions. Organic chemistry is the study of structure, properties, and reactions of organic compounds. Here are some examples of structures of organic chemistry:
2. Why was the Urey-Miller experiment so important (try to place a diagram or picture here)?
can you be more specific about the compounds involved, as well as the implications about the origins of life
The Urey-Miller experiment took place in 1953 permformed by Stanly Miller. The experiment was so important because it showed that an organic compound can be created in a laboratory with two inorganic compounds at the proper conditions. Miller used electrical discharges to trigger reactions in gasses such as, H2O, H2, NH3,and CH4 which are all released by volcanoes and found in nature. Miller was able to synthesize each of these organic compounds in his apparatus.

3. What is special about carbon that makes it the central atom in the chemistry of life (video or pictures)?
Carbon is the central atom because instead of becoming an ion, it shares its electrons (COVALENT) with other atoms, allowing it to be a central point from which a molecule can branch off in four directions, holding a chemical bond with other elements at the same time.
-Taihlor C
4. Upload pictures to contrast the three types of isomers.
Structural Isomers- They differ in covalent partners, and in their covalent arrangement of their atoms. Also, Structural Isomers differ in the location of the double bonds.
-Mike
Unbranched Branched
Geometric Isomers- Differ in the arrangement about a double bond. They have the same amount of atoms, however the structures differ in arrangement; creating a different geometric structure. This can occur when there is a restricted rotation in the molecule. - Dahlia M.
Enantiometers - Differ in spatial arrangement around an asymmetric carbon, resulting in molecules that are mirror images, like left and right hands.

5. Create a table below: For each functional group – upload a picture of the structure, name the compound, and note the functional properties –
A.Hydroxyl
Also known as Alcohols
Properties- its polar as a result of the electronegative oxygen atom drawing electrons towards itself; attracts water molecules, helping it dissolve organic compounds such as sugars
Example is Ethanol ^
B. Carbonyl
Also known as Ketones, or Aldehydes
Properties- a ketone and an aldehydes may be structural isomes with different properties as in the case for acetone and propanol
Example is Acetone ^
C. Carbonxyl
Also known as Carbonxylic Acids, or Organic Acids
Properties-has acidic properties because it is a source of hydrogen ions; the covalent bond between oxygen and hydrogen is so polar that hydrogen ions tend to dissociate reversibly; in cells, found in the ionic form, which is called a carbonxylate group
Example is Acetic Acid ^
-Amy D (btw my picture of ethanol wouldnt go on, i tried 2 diff pictures)
d. Amino
Compounds are known as amines.
An example is glycine (an amino acid).
Amino groups are made out of a nitrogen atom bonded to two hydrogen atoms (NH2). When amines are in a compound with caroxylic acids the compound with carboxylic acids, the compound is an amino acid. They can pick up protons from acids. In cells, they are cations.
e. Sulfhydryl
Compounds are known as thios.
An example is etanethiol.
Sulfyhydryl groups are made of a sulfur atom bonded to a hydrogen atom (SH). They can stabilize proteins
f. Phosphate
Coumpounds are known as organic phosphates.
An example is glycerol phosphate.
Phosphate groups are built out of a phosphate atom single-bonded to three oxygen atoms and double-bonded to another (OPO3^-2). They are key parts of energy molecules like ATP and ADP. The compounds they are attached to become anions. Phosphate groups are acidic.
